integration OpenCMS and Jforum

Good afternoon ladies and gentlemen, I beg your pardon for my language, I do not know much English. The essence of my question is this.
Need to integrate Jforum in OpenCMS.
User logs on to the website (Opencms) and can safely talk on the forum (Jforum).
How can we do?
Thanks for your support!

Welcome to CodeRanch! While JForum does have SSO (single sign on), I haven't seen anything for OpenCMS specifically. A search of this forum says it didn't exist at all in 2007. And I haven't seen anything to show it has since. Which means this may be more work than expected.
